Is NSL.SH open source?
Yes. NSL.SH is fully open source and available on GitHub.
- Repository: github.com/Yundera/mesh-router-root
- Protocol: WireGuard (encrypted, high-performance)
What NSL.SH does
NSL.SH is the tunneling and domain routing layer that makes your PCS reachable from anywhere:
- Domain routing — maps
appname-you.nsl.shto your PCS - WireGuard tunnel — encrypted relay for machines behind CGNAT or without a public IP
- Automatic HTTPS — TLS certificates via Caddy reverse proxy
Can I self-host the relay?
The code is open source, so technically yes. However, the managed NSL.SH service handles all the infrastructure (relay servers, domain management, certificate provisioning) so you don't have to.
